| 摘 要： | 对影响雷达天线罩风载体型系数分布的多种因素进行分析,提出了一种能反映高径比变化影响的四偶极子数学模型.通过对偶极子位置的优化处理,所得结果与迎风上半球面实测数据吻合良好.结合在工程设计中已经广泛采用的三次函数近似表达式,给出了不同高径比下天线罩整体风载体型系数计算公式,这些结果可以直接应用于天线罩的结构设计参数计算,并从理论上给出了原天线罩工程计算中不含高径比风载荷体型系数方程的误差.

| Abstract: | A four-dipole math model has been set forward to describe the variation of radome height-to-diameter ratio via analyzing several factors of wind load distribution.By optimizing the position of dipoles,the computational results are close to the experimental data on the upper part of the upwind sphere.Refer to the approximating cubic function,which is widely used for engineering design,a formula of wind load distribution was established to directly calculate the structure design parameters of deferent radome ... |
